ABSTRACT OF THE DISCLOSURE A zipper slider having a longitudinal trackon the outside of one wall extending substantially from one end to theother of the slider and means for attaching a pull tab to the slider sothe tab may move from one end of the track to the other end.

This invention relates to sliders for separable fastener stringers. Moreparticularly, the invention deals with the provision of an elongatedchannel on a wall of the slider for support and guidance of a swivelmounting for a pull in movement of the swivel mounting to each endportion of the slider, facilitating proper operation of the slider overthe stringers of the separable fastener in coupling and uncoupling saidstringers, thus avoiding the cocking or jamming of the slider upon thestringers.

Still more particularly, the invention deals in a structure of thecharacter defined, wherein an elongated washer, defining the channel ofthe slider, is mounted in a recess or depression of the slider wall andperipheral lip edges of the recess or depression are utilized inretaining the washer against displacement from the slider wall.

The novel features of the invention will be best understood from thefollowing description, when taken together with the accompanyingdrawing, in which certain embodiments of the invention are disclosedand, in which, the separate parts are designated by suitable referencecharacters in each of the views and, in which:

FIG. 1 is a diagrammatic perspective view of a slider made according tomy invention, part of the construction being broken away.

FIG. 2 is an enlarged plan view of the slider, with parts of theconstruction broken away and parts shown in section. I

FIG. 3 is a partial section on the line 3-3 of FIG. 2, with part of thebackground shown being illustrated in section; and

FIG. 4 is'a diagrammatic sectional detail view showing the slider wallas initially cast and indicating, in dot-dash lines, a section of thechannel forming washer, with the retaining lip shown in engagement withthe washer in dotted lines.

In the drawing, and 11 show conventional top and bottom walls of achannelled slider body, the walls being joined at the wide end thereofin a web 12, note FIG. 3.

With the present slider structure, the top wall 10 is fashioned to forman elongated and more or less elliptical recess or depression 13bordered by boundary walls 14 which are normally formed or cast, as seenin FIG. 4 of the drawing. Considering FIG. 2 of the drawing, the roundedend portions of the walls 14 are positioned adja cent opposed ends ofthe wall 10, as seen at 15 and 16, 15 being adjacent the narrowcontracted end of the Wall 10; whereas, 16 is adjacent the wider doublechannel-end of the slider.

At 17, I have shown an elongated channel forming washer, the peripheraledges of which fit snugly in the recess or depression 13 of the wall 10,as clearly noted in FIG. 3. This figure also shows the cross-sectionalcontour of the washer 17, in other words, the channel 18 on the lowersurface thereof, the elongated reduced diameter and more or lesselliptical opening 19 at the upper por- Patented Sept. 26, 1967 tion ofthe washer and the peripheral bevelled corner portions 20 at the top ofthe washer. Here, it is pointed out that, in making the assemblage,after the washer 17 has been placed in position, as indicated indot-dash lines in FIG. 4, the upper end of the wall 14 is formed overupon the bevelled surfaces 20 to formthe retaining lips 21, positivelyretaining the washer 17 against displacement from the wall 10.

Prior to forming the assemblage, as noted above, a swivel member or pin22 or its enlarged or flanged head 23 is positioned in the channel 18 ofthe washer 17, the pin 22 projecting freely through the aperture 19 ofthe washer and the upper end of the pin has, on opposed sides thereof,recesses or apertures 24 for the reception of pivot ends 25 of asuitable pull 26.

Considering FIG. 3 of the drawing, it will appear that the head 23 ofthe pin 22 fits freely in the channel 18 of the washer, thus permittingfree movement of the swivel pin from the position shown in FIGS. 1 and 2adjacent the rounded end 16 to the opposed end of the slider, in otherwords, adjacent the end 15, as noted in FIG. 2 of the drawing. Theposition of the swivel pin 22, shown in FIGS. 1 and 2 of the drawing, isthe position assumed when the slider is operating on stringers to couplethe same; whereas, in uncoupling the stringers, the swivel pin will bepositioned at the opposed end of the washer from that shown in FIGS. 1and 2 of the drawing. In addition to providing free swinging movement ofthe pull 26 on the pin, it will be apparent that the pull can be swungto rotate the swivel in the channel defined by the washer 17.

With the structure defined, it will be apparent that a definite andpositive channel structure can be formed on a slider body for free andeasy movement of the swivel pin in operation of the slider and, in someinstances, the channel washer can be formed of materials contrasting tothe material employed in the slider body.

With luggage and other articles of manufacture, quite often, a zipperoperating upon a surface is arranged to travel in directions at rightangles to each other and these two directions are usually joined by arounded portion, in which the stringer is arranged. With sliders of thekind herein disclosed, it has been found that the sliders will travelthrough these rounded stringer portions without any cocking or jammingby reason of the fact that the pull is capable of movement in thechannel to bring the swivel member in the proper end of the channel toprevent cocking or jamming; in other words, with the present structure,a freer action of the slider is provided along the stringer, regardlessof the contour or arrangement of the stringer on its support.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent is:
